FATIGUE RELIABILITY EVALUATION, UPDATING AND MAINTENANCE OF STEEL BRIDGE USING NONDESTRUCTIVE INSPECTIONS (NDI)

Fatigue is an important failure mode for steel bridges. A fracture mechanics-based fatigue reliability model is suggested which incorporates uncertainties from many sources, including uncertainty in the inspection outcomes. The method is calibrated with respect to the currently used S-N curve-based AASHTO method. Procedures are developed to update reliability after each inspection. Using the information on the updated reliability, several fatigue mitigation strategies are proposed for steel bridges.
